TO ALL WHOM IT MAY CONCERN:

.Be it known that I, GEORGE E. CUMnfc, of Lafayette, in the county ofTippecanoe, and State of Indiana, have invented a new and usefulimprovement in Automatic Car-Couplings; and I do h oreb declare thatthefollowing is a full, clear, and exact description of the same,reference being had to the annexed drawings, making part of thisspecification, in whieh- Figure 1 is a vertical longitudinal section.

Figure 2 is a perspective \"iew; and

Figure 3 is a plan of the shackle-bar.

The same letters are employed in all the figures in the indication ofidentical parts.

A is the draw-head, having a mouth with four converging sides,f'orming'a throat, through which the shacklebar "head passes into thechamber behind the same. In this chamber is hung the hinged piece B, theform of which is shown in fig. 1. This is in the general form of thebase and hypothenuse. of a right angled triangle; but the side formingthe hypothen'use is bent so as to form a recess at B,-with parallelsides, to hold the head of the shackle-bar.- This'piece 13 is hinged tothe base of the stirrup .C, the stems of which rise throughholcs in thetop of the draw-head, and are united by a cross-piece resting upon aspring, E, which is staunch enough to sustain the weight of all theparts, and may be of any convenient form. The bottom of the draw-headbelow the piece 13 is open; and a slot is cut through the lower side ofthe draw-head at A Longitudinal slots are cut in the head of theshackle-bar I), so that it may be used in connection with the ordinarydraw-head and pin. As the cars come in contact on approaching, theshackle-bar projecting from one draw-head will be directed by theinclined sides of the mouth A. Passing through the throat it will enterthe recess 13 at the base of the piece 13. When the shackle-bar is drawnupon, its shoulders will, bear against the back part of the mouth of thedraw-head on each side of the slot A Whenit is dcsired'to disengage theshackle-bar it is only necessar; to press down the stirrup C, therebypassing the lower side of the piece 13, and with it the shackle-bar,below the bottom of the draw-head, and disengaging the latter, thusuncoupling the ears. Should the cars be thrown from the track they woulddisengage themselves. Thestirrup mar be operated, by any convenientarrangement of rods or levers, from the top or other part of a carJ iWhat I claim asmy invention, and desire to secure by Letters Patent,is,- v

1. The combination, in an automatic car-coupling, of the draw-mead A,hinged piece B, stirrup O, and spring supporting the same, with theshackle-bar D, said parts being respectively constructed and arrangedsubstantially as set forth. i i

2. The draw-head A, when constructed with an opening through its lowerside A, for the escape of the shackle-bar, substantially as described. Iv i 3. The hinged piece 13, when constructed and used in combinationwith a draw-head and shackle-bar, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
